Asus RT-AC66U Merlin Stuck applying settings when manually assigning IP

[zeeblefritz]

I have an ASUS RT-AC66U with Merlin firmware that is behind another router with its own subnet. The main router is 192.168.0.1/24 and the Asus is 192.168.2.0/23 everything works fine but whenever I try to manually assign an IP the router just sits in "Applying Settings ..." and never actually sets the IP. Does anyone know why this might be?

What firmware version?

 

[zeeblefritz]

Looks like 380.70

 

[ColinTaylor]

Has this ever worked or is this a new problem?

You might have better luck if you stick with the normal /24 subnet size rather than /23.

 

[zeeblefritz]

So this has worked before but this is the first time being behind another router.

 

[ColinTaylor]

What is the IP address you're trying to manually assign?

 

[zeeblefritz]

192.168.2.102 is one of them, the device already has the IP and is recognized and auto populated by the router when doing the assignment.

What's the available NVRAM situation?

Sorry, I don't fully understand the question. If I ssh to the router and execute 'nvram show' it gives me a crapload of data. On the GUI I see 176MB free.

Look at Tools - System Information > NVRAM usage

I wasn't sure this page was available in this old firmware.

49878 / 65536 bytes

This is not the issue then. Try restoring the original /24 subnet as suggested above.

 

[zeeblefritz]

even 192.168.2.0/24 does not commit.

Maybe a browser addon issue? Try a different PC/browser or "private" mode.

 

[zeeblefritz]

I use Brave so that is the first thing I tried. Tried Chrome from Windows on WiFi and Firefox on Ubuntu on ethernet.

When all else fails, time for a factory reset and manual reconfiguration. Given enough time, some devices just work themselves into a bad state.

 

[zeeblefritz]

I had already done a reset through the GUI, do I need to do an even more thorough reset?

No, provided you did NOT subsequently reload a prior backup. That negates the purpose of the factory reset.

Although very rare, there's an ever so slight chance the firmware itself has become corrupted. You might try reinstalling the firmware as a last resort. Or maybe the nvram flash is beginning to fail, esp. given the age of the router.

P.S. You might want to dmesg the router for any such relevant messages.
